It makes me dizzy, to think of the Vatican--of its wilderness of statues, paintings, and curiosities of every description and every age. The “old masters” (especially in sculpture,) fairly swarm, there. I can not write about the Vatican. I think I shall never remember any thing I saw there distinctly but the mummies, and the Transfiguration, by Raphael, and some other things it is not necessary to mention now. I shall remember the Transfiguration partly because it was placed in a room almost by itself; partly because it is acknowledged by all to be the first oil painting in the world; and partly because it was wonderfully beautiful. The colors are fresh and rich, the “expression,” I am told, is fine, the “feeling” is lively, the “tone” is good, the “depth” is profound, and the width is about four and a half feet, I should judge. It is a picture that really holds one’s attention; its beauty is fascinating. It is fine enough to be a Renaissance. A remark I made a while ago suggests a thought--and a hope. Is it not possible that the reason I find such charms in this picture is because it is out of the crazy chaos of the galleries? If some of the others were set apart, might not they be beautiful? If this were set in the midst of the tempest of pictures one finds in the vast galleries of the Roman palaces, would I think it so handsome? If, up to this time, I had seen only one “old master” in each palace, instead of acres and acres of walls and ceilings fairly papered with them, might I not have a more civilized opinion of the old masters than I have now? I think so. When I was a school-boy and was to have a new knife, I could not make up my mind as to which was the prettiest in the show-case, and I did not think any of them were particularly pretty; and so I chose with a heavy heart. 

Follows is an anecdote about a knife young Sam Clemens once purchased. (See The innocents Abroad: Chapter 28).
